Revegetation is a broad term that describes a variety of practices that we use to modifying vegetation. A typical revegetation effort involves three general components: a disturbance to create a niche to introduce new species, propagation of that species onto the site with seeds, cuttings, or rooted stock, and some kind of aftercare (either supplemental water and nutrients, or more disturbance) to favor the introduced species. While we are focused on discrete projects, revegetation occurs in the context of natural vegetation evolution, driven by climate, hydrology, genetics, dispersal, competition, stress, and ongoing disturbance regime. This page is a master topic page to organize information on the wiki to support revegetation practice.

• category:flora pages are used to gather information on individual plant species, organized by genus.

Shared Resources

• File:Aubry & Potash 2007 olympic native plant notebook.pdf is perhaps the best free reference produced in our region on revegetation.
• The Ecosystem Guild has a native plant list (link to Google Sheet) that integrates USACE wetland indicators and site indicators published by Klinka et al 1989.

Species Composition

What resources do we have for designing target vegetation composition?

• DNR Natural Heritage Program provides a range of reports describing composition of natural vegetation.
• File:Chappell 2004 upland plan associations puget trough.pdf - in particular provides a voluminous list of common co-occurring plant communities observed in lowland Puget Sound.

Freshwater Tidal

There are notably few resources for designing composition and structure of freshwater tidal vegetation.

• Kunze & Cornelius 1982 provides a characterization of community composition in columbia river "surge plain" wetlands.
• File:Cereghino 2004 freshwater tidal revegetation zones.pdf offers an analysis of freshwater tidal data using inundation duration as a basis for zonation as a surrogate for redox.

Disturbance and Soil Restoration

How to we create space in the field suitable for propagation?

• Moffat & Bending 2000 describe methods for soil replacement to minimize compaction.

Propagation and Planting Technique

How do we efficiently introduce species into a vegetation?

• Cutting and Livestake Production, Processing and Installation is a topic page focused on livestakes and use of unrooted cuttings in the field, and is currently holding materials for biotechnical erosion control.

Aftercare Strategies

How to we favor target composition after propagation?

Regional Suppliers

Evaluation and Monitoring

How do we qualitatively and quantitatively observe vegetation?
